Symmetry issue

[Klapaucius]

The symmetry is concentrated on the one part and not on the whole craft.  Interstingly, it was a problem on the nose cone, but worked fine when I tried attaching the strut to the fuel tank instead.

This is again an issue that was solved in KSP 1 already. It sometimes still happens in 1.12, but only very rarely.

From the look of it, even with two objects side joined end to end like conical sections joined upside down under the 2XL round Hydrogen tank... the struts align their symmetry to the part being attached to. So if you flip the parts around, the "order" (not sure what else to call it) of each struts location, is located on the target part automatically in a specific order that is reversed when you flip a part around, and I suspect similar behavior is happening with the weird targeting for struts to side boosters.  I've got screenshots if the "order" symmetry stuff isn't entirely obvious and some visual help is needed.
